AMQPClassic Tasks

Properties   Configuration Settings  

An easy-to-use AMQP 0.9.1 client implementation, with support for RabbitMQ extensions.

Remarks

The AMQPClassic task provides an easy-to-use AMQP 0.9.1 client implementation, and it also supports certain RabbitMQ extensions to the AMQP 0.9.1 specification. The task supports both plaintext and TLS-enabled connections over TCP.

Connecting

The AMQP 0.9.1 transport protocol has two layers: an overall connection between the client and server, and one or more channels running over that connection.

AMQPClassic Send Task

At a minimum, you must supply an RemoteHost, RemotePort, and ChannelName for the connection. In order to authenticate with the AMQPClassic broker you will need to specify a User and Password. The AuthScheme property contains a preferential list of authentication methods to be enabled on the task.

Setting ChannelName will create a channel with the specified name on the broker. Once the task has connected to the server it is possible to manipulate exchanges and queues and publish messages.

The task will send the contents of the MessageBody property.

The AMQPClassic Sender and Receiver Tasks have support for SSL transport layer security. This may be enabled by setting SSLStartMode, SSLCert and SSLAcceptServerCert to appropriate values.

Declaring Exchanges

Set DeclareExchange to true to declare an exchange. ChannelName, ExchangeName, ExchangeType, ExchangeType, ExchangePassive, and ExchangeAutoDelete may also be set.

Declaring Queues

Set DeclareQueue to true to declare a queue. ChannelName, QueueName, QueuePassive, QueueDurable, QueueExclusive, and QueueAutoDelete may also be set.

Binding Queues to Exchanges

Set BindQueue to true to bind a exchange with specified RoutingKey.

Creating Consumers

The receiver task will use the Consumer properties to start a consumer for QueueName.

Sender Property List


The following is the full list of the properties of the sender task with short descriptions. Click on the links for further details.

AppIdThe Id of the application that created the message.
AsynchronousModeIndicates whether the server handles the request in asynchronous mode.

ContentEncodingThe content encoding of the message's body.
ContentTypeThe content type (MIME type) of the message's body.
CorrelationIdThe correlation Id of the message.
DeclareExchangeThis is used to verify that an exchange named ExchangeName exists, and potentially creates it if no such exchange exists.

DeleteExchangeSpecifies whether delete the exchange named ExchangeName.
DeleteQueueDeletes a queue.
DeliveryModeThe delivery mode of the message.
ExchangeAutoDeleteThis specifies whether the server should automatically delete the exchange when all queues have been unbound from it.
ExchangeDurableThis specifies what happens to the exchange in the event of a server restart.
ExchangeIfUnusedSpecifies whether the server will delete the exchange if no queues are bound to it.
ExchangeNameThe name of the exchange.
ExchangePassiveThis specifies how the server will deal with a preexisting exchange.
ExchangeTypeThis specifies the exchange type.
ExpirationThe time-to-live value for this message.
FirewallA set of properties related to firewall access.
HeadersHeaders associated with the message.
ImmediateControls what the server should do if the message cannot be immediately delivered to any consumer.
LogFileThe file to write logging information to at runtime.
LogModeWhat information gets logged during task execution.
MandatoryControls what the server should do if a message cannot be routed to any queue.
MessageBodyThe message body.
MessageIdThe unique Id of the message.
MessageTypeThe message's type.
OtherDefines a set of configuration settings to be used by the task.
PasswordA password to use for SASL authentication.
PersistentConnectionInstructs the task whether to keep the connection to the server open.
PriorityThe priority of the message.
PublishConfirmsEnables publish confirmations mode for a channel.
QueueAutoDeleteThis specifies whether the server should automatically delete the queue when all consumers have finished using it.
QueueDurableDurable specifies what happens to the queue in the event of a server restart.
QueueExclusiveExclusive , if True , indicates that the queue may only be accessed by the current connection.
QueueIfEmptySpecifies whether to delete the queue when consumers are attached.
QueueIfUnusedSpecifies whether to delete the queue when no messages are in it.
QueueNameThe name of the queue.
QueuePassiveThis specifies how the server will deal with a preexisting queue.
RecoverRequests the server to redeliver all messages on a given channel that have not been acknowledged.
RemoteHostThe address of the remote host. Domain names are resolved to IP addresses.
RemotePortThe port of the AQMP server (default is 5672). The default port for SSL is 5671.
ReplyToThe address to send replies to for the message.
RequeueThis property controls how the server should attempt to redeliver the messages awaiting acknowledgement.
RoutingKeyThe RoutingKey parameter specifies the binding's routing key.
RuntimeLicenseSpecifies the task runtime license key.
SSLAcceptServerCertInstructs the task to unconditionally accept the server certificate that matches the supplied certificate.
SSLAcceptServerCertAcceptAnyTells the task to accept any server certificate.
SSLCertThe certificate to use for client authentication during the SSL handshake.
SSLStartModeDetermines how the task starts the SSL negotiation.
TimeoutA timeout for the task.
TimestampThe message's timestamp.
TransactionModeWhether the channel is operating in Transaction mode.
UnBindQueueUnbind the queue to the exchange with given RoutingKey.
UserA username to use for SASL authentication.
UserIdThe identity of the user responsible for producing the message.
VirtualHostThe virtual host to connect to.
